Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-3, the good valve of a kind of leakproofness, including valve body 1, the top of valve body 1 are provided with valve deck 2, valve deck 2
Center vertical direction on be provided through valve rod 3, the top of valve rod 3 is provided with handwheel 4, fixed on the middle part outer wall of valve rod 3
It is provided with cover board 5, the inner bottom wall center of valve body is provided with fixed block 6, and the arranged on left and right sides of fixed block 6 is provided with flexible
Guide rod 7, two flexible guide rods 7 are symmetrical arranged, and the other end of flexible guide rod 7 is fixedly installed baffle 8, the other side of baffle 8
Be provided with sealing ring 9, the medial center of baffle 8 is fixedly installed limited block 10, and limited block 10 is prism structure, valve body 1 with
Valve deck 2 is fixedly connected by screw, and rubber washer is provided among the two, and the outer wall of valve rod 3 is provided with screw thread, sets on valve deck 2
The threaded hole set is adapted with the screw thread of valve rod 3, and the roof and bottom wall of cover board 5 pass through screw and be fixedly installed gasket seal
11, the guide rod 7 that stretches includes sleeve, and sleeve inner is provided with spring, and the other end of spring is fixedly installed guide rod, guide rod it is another
